## Abstract We consider a linear system of the form __A__~1~__x__~1~ + __A__~2~__x__~2~ + ฮท=__b__~1~. The vector ฮทconsists of independent and identically distributed random variables all with mean zero. The unknowns are split into two groups __x__~1~ and __x__~2~. It is assumed that __A____A__~1~ h

In this paper, we propose a method to generalize Strang's circulant preconditioner for arbitrary n-by-n matrices A,,. The 181th column of our circulant preconditioner S,, is equal to the 151 th column of the given matrix A,,. Thus if A,, is a square Toeplitz matrix, then S,, is just the Strang circu
For linear least squares problems min x Ax -b 2 , where A is sparse except for a few dense rows, a straightforward application of Cholesky or QR factorization will lead to catastrophic fill in the factor R. We consider handling such problems by a matrix stretching technique, where the dense rows ar
## Abstract The MichaelisโMenten kinetics is fundamental in chemical and physiological reaction theory. The problem of parameter identification, which is not well posed for arbitrary data, is shown to be closely related to the Chebyshev sum inequality. This inequality yields sufficient conditions f
